Writing Barcodes

Take the following steps to add code to an existing project that will let you to write barcodes:

1.	Start with the program you created in Reading Barcodes.
2.	Define the following global IDs in Ezfunc.h in the BarcodeTutor directory:

#define IDM_WRITE_BARCODES 201

3.	Edit EZFUNC.RC file in the BarcodeTutor directory and add the following lines:

MAIN_MENU MENU

BEGIN

...

...
MENUITEM "Write Barcode" IDM_WRITE_BARCODES

END

4.	In the MainWndProc procedure, add the following code to the switch statement for WM_COMMAND:

      case IDM_WRITE_BARCODES:
         {
            BARCODE1D Bar1d;

memset(&Bar1d, 0, sizeof(BARCODE1D));

Bar1d.uStructSize = sizeof(BARCODE1D);

Bar1d.bErrorCheck = TRUE;

Bar1d.bOutShowText = TRUE;

BARCODEDATA BarData;

memset(&BarData, 0, sizeof(BARCODEDATA));

BarData.uStructSize = sizeof(BARCODEDATA);

BarData.nUnits = BARCODE_SCANLINES_PER_PIXELS;

SetRect(&BarData.rcBarLocation, 100, 100, 350, 200);

BarData.pszBarCodeData = "012345678901";

BarData.nSizeofBarCodeData = (L_INT)strlen(BarData.pszBarCodeData);

BarData.ulType = BARCODE_1D_EAN_13;

BARCODECOLOR BarColor;

memset(&BarColor, 0, sizeof(BARCODECOLOR));

BarColor.uStructSize = sizeof(BARCODECOLOR);

BarColor.dwColorBar = RGB(0, 0, 0);

BarColor.dwColorSpace = RGB(255, 255, 255);

L_INT nRet = L_BarCodeWrite(&LeadBitmap,

&BarData,

&BarColor,

0, &Bar1d, NULL, NULL, NULL, NULL);

if (nRet == SUCCESS)

InvalidateRect(hWnd, NULL, TRUE);

else

               MessageBox(hWnd, TEXT("Failure during writing linear barcodes"), TEXT("Error!"), MB_OK);
         }
         break;

5.	Build SimpleLoad.exe.
6.	Run SimpleLoad.exe.
